Species | |
Narnavirus is a genus of positive-strand RNA viruses in the family Narnaviridae. Fungi serve as natural hosts. There are two species in this genus.[1][2] Member viruses have been shown to be required for sexual reproduction of Rhizopus microsporus.[3] Narnaviruses have a naked RNA genome without a virion and derive their name from this feature.[4]
Virology
Structure
Narnaviruses have no true virion. They do not have structural proteins or a capsid.[5]
Genome
Narnaviruses have nonsegmented, linear,
Replication cycle
Viral replication is cytoplasmic. Replication follows the positive-strand RNA virus replication model. Positive-strand RNA virus transcription is the method of transcription. The virus exits the host cell by cell-to-cell movement. Fungi serve as the natural host. Transmission routes are parental and sexual.[2]
Taxonomy
The genus has the following two species:[1]
